CAR-SEAL.

Specication of Letters Patent.

Application filed March 11, 1916. Serial No. 83,519.

To all whom t may concern:

,a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Car-Seals, of which the following is a specification.

, My invention relates` to an improved car seal, and `it consists in theconstructions, combinations and arrangements herein described andclaimed. f

An object of my invention is to provide an improved car seal providedwith automatic double locking and .guiding devices, which positivelyprevent release or detachment of the seal without destruction of thelatter.

A further object of my invention is to provide a strong and simple carseal which will be certain in action, and in which neither end of thestrap can be broken off and then reinserted in the seal case.

In the accompanying drawings: Figure 1 is a top face view showing theseal case and adjacent portion of the strap in one embodiment of myinvention; Fig. 2 is a face view of the shackle end of the strap; Fig. 3is an edge view of my improved seal in unsealed position, the seal casebeing shown in section along the line 3 3 of Fig. 1; Fig. 4 is a similarView showing the strap in locked line 5-5 of Fig. 1; Fig. 6 is a topview of the resilient locking member, partly broken away for clearness;Fig. 7 is a view similar to Fig. 3, showing a slight modification; andFig. 8 is a top face view of the-seal case shown in Fig. 7

Referring to the drawings, 1 indicates a locking strap having a shackleend 3 of reduced width provided with notches 4L to form a locking head5. The other end of said strap is bent over to form an integral sealedcase 6, the longitudinal edges 7 of said case being strongly crimpedtogether, and preferably spotavelded at 8 adjacent to the ends of theentrance slot 9 adapted to closely t the reduced shackle end 3 of thestrap. The strap l is provided with embossed portions, or projections,19 and 20 adjacent to its respective ends, in order to prevent saidstrap being broken and its ends then surreptitiously forced through theentrance slot 9 of the case 6.

A resilient member 10 is firmly confined within the seal case 6 andformed with a forwardly-extending portion 11 providec with projections12 for lockingly engaging thev head 5 in theV sealed position of thestrap; said locking projections being provided with inclined front edgesto facilitate such engagement of the head therewith. The resilientmember 10 is furtherformed with a pair of rearwardly-extending, spaced,auxiliary locking lugs 13 adapted to interlockingly engage the straphead 5 upon the initial insertion thereof into the casing 6 and to guidesaid head into position for engagement* with the locking projections 12.The casing 6 is formedwith Vrecesses 11 for receiving the spring lugs 13and for per-y mitting passage of the strap head 5 past the ends of saidlugs into interlocking engagement therewith. The lower wall of thecasing is provided with an inwardly-projecting inclinedshoulder 15 forinsuring positive locking engagement of the strap head 5 with thelocking projections 12, and to constitute a stop for preventingexcessive downward shifting of the forwardly-projecting portion 11 andauxiliary locking lugs 13 by the strap head 5 bearing thereon during itsinsertion.

In the above description, it will be clear that in the operation of myinvention the shackle end of the strap is inserted through the entranceslot 9 of the casing 6 until the strap head 5 rides over the ends of thespring lugs 13. The strap is then slightly withdrawn until the head 5 isguided by said spring lugs 13 into position to be shifted into lockingengagement with the projections 12; the strap being then again pushedforward within the casing until said projections l2 are brought intolocking engagement with said head 5 and the strap thus positively heldlocked in position.

Figs. 7 and 8 illustrate a slight modication, in which the top wall ofthe seal casing is cut partly across at 16 and the portion 17 of'saidwall in front of said cut is bent down to provide an entrance slot 18v-there- Patented Oct. 24, 1916. i

above for the shackle end of the strap. This and satisfactoryconstructions, but changes could be made Within the spirit and kscope ofmy invention.

I claim :4- l. Ina Acar sea-l,- a metal strip having one end formed witha locking head, the other end of, said strip being bent over and securedalong its edges to the body of the strip to `forni a casing, said bentover portion being transversely cut across a portion only of its Widthand having that portion between the strip end and such transverse cutdepressed to provide an entrance slot above said depressed portion forthe locking head, and means within said casing for lockingly engagingsaid head.

2.. In a car seal, a metal strip having one end lormed with a lockinghead, the other' end ot" said strip being bent over and secured alongits edges to the body of the strip toforma casing, said bent overportion beking transversely cut across a portion only of its Width andhaving that portion between the strip end and such transverse out de--pressed and spot Welded to the body of the stripto provide an entranceslot above said depressed portion for the locking head, and

means Within said casing for lockingly engaging said head. c

y 3. In a car seal, a metal strip having one 3 end reduced in width andformed With a locking head, the other end of said strip being bent overand secured along its edges to the body of thestrip to form a casing,"said bent over portion being transversely cut 3 across a portion only ofits Width and hav-k ing that portionbetween the strip end and suchtransverse cut depressed and spot Welded to the body of the strip toprovide an entrance slot above said depressed portion of 4 proper Widthfor snugly receiving said reduced end'of the strip, and a member Withinsaid casing provided with means for lock* ingly engaging said head andwith auxiliary means for initially interlockingly engaging 4 saidheadand guiding the latter' into locking engagement with said locking means.

In testimony whereof I affix my signature in the presence of twoWitnesses.
